KTM's four-wheeled future

By Ben Purvis Motor Industry 25 February 2008 11:26 KTM's X-Bow track day car is just the start of a five-model line-up that will include Dakar and Le Mans endurance racers.

The Opel/Vauxhall Cascada effectively replaces the Astra Twin Top, but attempts to move the model upmarket as a separate product line. It has moved up a size to reflect its prestige aspirations: at 4,697 mm long and 1,840 mm wide, it's longer than an Audi A5. Like many of the latest generation of convertibles, the Cascada ditches a folding solid hardtop in favor of a lighter, more space-efficient and cheaper soft fabric set-up.
